Title: Clock signal correction circuit
Inventor: TOMIZAKI TOME
IPC: G11B20/10
Filed: 1993-02-23
Abstract: PURPOSE:To make a clock signal accurately follow the eccentricity of a disk by correcting the phase or the frequency of the clock signal in accordance with a stored disk eccentric quantity. CONSTITUTION:Eccentric quantity data inside a storage section 26 is read synchronized with the rotation of the disk, converted into a speed signal by a feed forward compensator 29 after converted by a D/A converter 28 and feed- forward impressed additionally as the control voltage of the VCO 35 of a PLL circuit 30. Thus, the VCO 35 is controlled by not only an output from a phase comparator 31 but also a track circular eccentricity display voltage arriving via a switch 34 from the storage section 26. Therefore, the VCO 35 is followed by a closed loop operation generated from the disk and an open loop operation is carried out as well by a signal from the storage section 26 for predicting a current time eccentricity quantity.
